The porcine pseudorabies virus (PRV) leading to severe neurological and respiratory damage can infects a wide range of vertebrates and humans, which raises concerns regarding the potential cross-species transmission of PRV. However, there is currently a lack of specific antiviral treatments available for PRV. In this study, we designed and synthesized 25 dimer derivatives containing N-pyridine bipyrazole moiety based on the principles of molecular splicing and electron isoarrangement. The structures of these compounds were characterized using 1H NMR and 13C NMR analysis. Preliminary bioassay revealed that most of the compounds exhibited potent anti-PRV activity at a concentration of 10 μM while demonstrating no or minimal toxicity towards PK-15 cells. These novel N-pyridinium bipyrazole dimer derivatives could be regarded as anti-PRV agents for further optimization and development.

Key words: N-pyridinium bipyrazole, dimer derivatives, anti-PRV virus activity
